3 Claims.

The prment invention relates to apparatus for fluid treatment of yarn packages and the like, and, more particularly, relates to apparatus; for uniformly yeing and/or drying the packages! Yarn packages, which are to be dyed or subjected to. other fluid treatment, usually are wound on a fiangeless, perforated, hollow cylindrical tube to provide a cylindrical package generally known as a cheese. Due to the inherent factors involved in winding the yarn by means of winding machines of the type generally in service, the package decreases in density from the tube to the outer eriphery thereof. Consequently when the package is dyed, for example, by means of apparatus of the type disclosed in my prior -United States Patent No. 2,250,085, wherein the dyeing medium is introduced alternately from the tube and the outer periphery of the package, the more densely wound zones, of the package retard the passage of the dyeing medium there. through, whereby a zone of the package between the inner and outer peripheries may be dyed insufliciently or the package is otherwise non-uniformly dyed.

Accordingly, an object of the present invention is to provide apparatus which overcomes the foregoing difliculties and disadvantages.

Another object is to provide apparatus which adjusts the density of the package to insure uniform dyeing or other fluid treatment thereof.

Another object. is to provide such apparatus wherein the passage of the dye liquor or other fluid treating medium through the package adjacent. the sides thereof is more accurately controlled.

Another object is to provide such apparatus which is. adapted for use in existing package dye.- ing or other fluid treating apparatus.

A further object is to accomplish the foregoing in an extremely simple and economical manner.

Other and further objects will be obvious upon an understanding of the illustrative embodiment about to he described, or will be indicated in the appended claims, and various advantages not re ten-ed to herein will occur to one skilled in the art upon employment of the invention in practies.

In accordance with the invention, the foregoing bjects are accomplished by providin pression plates comprising means for mounting the same adjacent the ends of the tube and an annular zone for engaging the sides of the package which 'zone is flared towards the other end of the package from the tube to the outer periphery of the package to thereby apply proeressively increasing compression at the si e o henackase. from the inner periphery to theioutcr periphery thereof, whereby the density or the ackage is adjusted to render'the samesubstan tially uniform. This annularzone may be substantially straight or arcuate in cross-section.

In a preferred embodiment about to be described, the plate mounting means constltutes'a cup-shaped portion for receiving an end of the tube, which portion is centrally apertured for the reception of a spindle and which portion has axially outwardly extending means; he tu e has means for centering the same on the spindle in spaced relation thereirom; and a stop and a .removably secured nut are provided adjacent the respective ends of the spindle for positioning'the lates to effect compression of the package, the stop and nut being provided with a recess for recepti n of the axially extending means. The plate further are provided with one or more passages extending lfrom the tube to the outer periphery of the package for try-passin the y liquor or other treating fluid therethrough.

In the drawing:

F g l is an end view of apparatus illustrating an embodiment of the invention, with a portion of one of the plates broken away and a portion of the tube being shown in section.

Fig. 2 is a sectional view taken along the line 2-2 on Fig 1.

Fig, 3 is a side view, partly in elevation and partly in section illustrating another embodiment of the invention.

Referring to the drawing in detail and more particularly to Fi s. 1 and 2, there is shown apor tion of a wall In of a conduit within a dyeing t nk, such as shown in my aforementioned patcut. The wall is formed with a threaded enerture H into which is secured a bushing 12 having one end of a hollow perforated spindle ll fixed therein. The bushing 12 is formed at its upper end, as. viewed in Fig. 2, with an annular recess or groove l5 surrounding the spindle, and the other end of the spindle His formed with a threaded zone IS.

A yarn package. I! is supported by the spindle M, which packa e generally comprises a perfo rated hollow cylindrical tube is, and a cylindrical cheese of: yarn wound on the tube havinga deny suitabl ior dyeing or other fluid treatment hereof. The tube I 8, as shown ingF-ie. 2, has-a centrally nertured axially inwardly c pped non tion. 20.2 at. each. end thereofscrcingasen adapter for centering the tube on the spindle in spaced relation thereto.

In order to adjust the density of the yarn to render the same substantially uniform, a compression plate 21 is provided at each side of the package. Each plate is formed with a central, axially outwardly extending cup-shaped portion 22 adapted to receive an end of the tube [9. Each plate is also formed with a central aperture for receptiorr-of;-the spindle, which aperture isdefined byan axially outwardly extending annular flange 24.

The lower plate, as viewed, has its flange 24 seated in the recess 15 of the bushing I2, whereby the bushing serves as a stop or mounting support for one end of the package.

The upper plate has its flange 24 seated in an annular recess or groove 25 of a nut 26 removably secured to the threaded zone l6 of the spindle, whereby the package is mounted between the compression plates and is supported on the spindle. ,Since the depth of the cupshapedportions 22 determines the extent of movement of the plates towards each other, when the nut 26 is applied, the plates will compress the package uniformly in every instance.

As shown in Figs. 1 and 2, the plates are formed with an annular zone 2'1 for engaging a side of the package, which zone is flared slightly towards the other end of the package from the outer periphery of the tube to the outer periphery of the package. In this embodiment of the invention, the zone is substantially straight and is disposed at an angle to the horizontal, as viewed. Preferably, the plates extend outwardly beyond the outer periphery of the package and are formed with a curled edge portion 29 serving to, stiffen the plates.

The plates 2|, by reason of the foregoing described construction, are adapted to apply progressively increasing compression at the side of the package from the inner periphery to the outer periphery thereof. In this manner, the inner zone of the package having the greater density is compressed the least and the outer zone having the lesser density is compressed, the most, whereby the density of the package is adjusted to render the same substantially uniform. Since the variation in density of the packages wound ona given winding machine is always about the same due to the inherent nature of the winding operation and can be determined, an angle of taper of the zone 21 is chosen which compensates for such variation. The straight zone, as shown in Fig. 2, is most suitable for use in connection with packages where the variation in density is approximately a straight-line function.

In Fig. 3, another embodiment of the invention is shown, wherein elements corresponding to similar elements shown in Figs. 1 and 2 have like reference numerals applied thereto. This embodiment differs from the embodiment shown in Figs. 1 and 2 in that the plates have an arcuate or curved zone 30, which is most suitable for use inconnection with packages where the variation in density is a function other than a straight line function. The exact shape of the curvature is selected to correspond substantially to the function of the density variation.

The platesZl, as described hereinbefore are further provided with a plurality of circumferentially spaced radial passages at the side engaging'the package formed by grooves or flutes 31. which extend from thetube [8 outwardly to or beyond the outer periphery of the package. These passages provide for flow of dye liquor, drying air, or other treating fluid from and to the tube through the side zones of the yarn adjacent the plates. The passages thus insure more uniform treatment of these zones of yarn which in some instance have a slightly greater density than the intermediate or middle zone of the yarn because of thegreater tension at which the yarn is applied at the sides of the package by reason of the winder traverse reversing its direction of travel.

From theforegoing description, it will be seen that the present invention provides apparatus for adjusting the density of yarn packages and to otherwise compensate for inherent irregularities in the package whereby more uniform dyeing or other fluid treatment is made possible. This is accomplished in a simple, practical and economical manner, and without the requirement of skill or guess work on the part of the operator.

The term yarn is used herein in a generic sense and is intended to include filaments, either natural or manufactured, as well as, assemblages of fibers or filaments, twisted, laid or braided together.

As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matters are to be interpreted as illustrative and not in any limiting sense.

What is claimed:

1. In apparatus for fluid treatment of a yarn package, the combination of a perforated tube on which the yarn is wound, a perforated spindle extending through said tube, each end of said tube having a centrally apertured, inwardly cupped portion for centering the tube on the spindle in spaced relation thereto, and a pair of compression plates each having means for mounting the same adjacent one end of said tube and having an annular zone for engaging a side of the package flared towards the other side of the package from the outer periphery of said tube to the outer periphery of the package to thereby apply progressively increasing compression at the side of the package from the inner periphery to the outer periphery.

2. Apparatus according to claim 1, wherein said zone of said plates is arcuate in cross-section.

3. Apparatus according to claim 1, wherein said zone of said plates has a plurality of circumferentially spaced grooves therein extending radially from said tube to the outer periphery of the package.
